A Caregiver's Guide to Understanding latest CLL treatments for Older Adults Living With CLL

A caretaker for a senior with CLL is often much more than a conduit to appointments and drugs. Many caregivers want to know why a particular drug is being prescribed, what other options there are and how the various treatments will impact the person with CLL in their daily lives.

There are many new treatments being given to people with CLL. Many of these are being used as targeted treatments. They may be used alone or in various combinations, depending on the patient and disease characteristics. Despite availability of multiple new treatments, there are many factors that must be taken into consideration to choose the appropriate treatment option.

What Is CLL?

Chronic Lymphocytic Leukaemia or CLL is a form of blood cancer characterized by presence of abnormal lymphocytes. These are a type of white blood cells which, in people with CLL, slowly start to multiply in the blood, in the bone marrow where all the blood cells are produced, and in the lymphatic system of tissues and organs throughout the body. It tends to develop in middle aged or older people.

However, the majority of individuals with CLL are asymptomatic at the time of diagnosis and are therefore monitored on an active surveillance or watchful waiting basis until such time as the disease progresses and requires treatment.

In summary, while there are times when CLL needs to be treated, there are also times when regular monitoring is enough. When there are signs of progression, or symptoms, then treatment may be indicated. At that time, enlarged lymph nodes, and low blood counts, as well as fatigue, night sweats, unexplained weight loss, and fever, can be symptoms which indicate the need for treatment.

Why CLL Treatment Can Be Different for Older Adults

Two people of the same age have very different physical, mental, social and financial circumstances. Hence treatment decisions are based on more than age of patient.

For an older adult, clinicians may consider:

     Overall physical health and functional ability

     Other medical conditions and medications

     Kidney and liver function

     Blood-cell counts

     CLL stage and rate of progression

     Genetic findings, including TP53 abnormalities and del(17p)

     Previous CLL treatment

     Risk of infections and other treatment-related complications

     The person's preferences and ability to manage treatment

Geriatric assessment is done to evaluate physical function, cognitive status, nutrition and social support to aid cancer treatment decisions.

The assessment for a geriatric patient with CLL will likely differ greatly from that of a younger patient with the same diagnosis. The results can help the patients and caregivers in evaluating treatment options.

What Are the Latest CLL Treatments?

Treatment for CLL is increasingly moving towards targeted therapy using a medicine that in turn uses a particular protein to kill CLL cells.

BTK Inhibitors

The Bruton tyrosine kinase (BTK) inhibitors are a class of targeted therapy for CLL.

Examples include:

     Acalabrutinib

     Zanubrutinib

     Ibrutinib

These types of therapies can inhibit the BTK protein and other related proteins which affect the B-cell in terms of development and in the CLL cell in terms of survival.

Additionally, while latest CLL treatments are administered via oral tablets or subcutaneous injection rather than via an IV line and infused into a vein over hours, these novel oral therapies can cause significant side effects and have drug-drug and drug-food interactions, requiring the monitoring of such issues as the patient’s blood counts, cardiac function, risk of bleeding, risk of infection, and other treatment-related adverse effects.

Venetoclax-Based Treatment

Venetoclax is a BCL-2 targeted therapy. BCL-2 is a protein that certain cancer cells use to survive. The most common use of Venetoclax in CLL is in combination with other therapies such as obinutuzumab and rituximab.

Venetoclax is being given in a new manner in order to decrease the risk of developing TLS (Tumor Lysis Syndrome) during the early dose-escalation period of treatment. Normal laboratory values and gradually increasing doses of venetoclax will be a cornerstone of its early administration.

Caregivers should be especially vigilant in following a treatment plan that involves a monitoring schedule for a treatment like venetoclax.

Acalabrutinib Plus Venetoclax

The CLL treatment landscape has evolved significantly in recent years. For example, in February 2026 the U.S. Food and Drug Administration approved acalabrutinib in combination with venetoclax for CLL treatment.

Targeted treatments are designed as per patient and disease characteristics. Approval of a combination of cancer drugs by the FDA does not automatically mean that it will be the an appropriate treatment option for a particular patient with CLL. Rather, it will be one of the many considered for an individual patient on the basis of their disease, medical history, other drugs that they are taking, how they tolerate individual drugs, and their preferences.

What Happens When CLL Comes Back?

Even after treatment has seemingly been effective, CLL can return at a later time, and treatment options that are relevant for patients with relapsed CLL are largely based on the prior treatments that have been used.

Pirtobrutinib is a non-covalent BTK inhibitor. Recently, pirtobrutinib was approved by the FDA for the treatment of adults with CLL or SLL who have had prior treatment with a covalent BTK inhibitor.

There are many other treatments, including new targeted therapies and treatment combinations, that are being investigated for patients with CLL that has become resistant to treatment. These are often investigated in the context of a clinical trial.

Why Genetic Testing Matters

Just as every person with CLL is different, so too is every person’s CLL. The differences can be in terms of the individual’s prognosis and in terms of the choices for treatment. Certain genetic and molecular features of the cancer can affect both.

Among the key findings that can guide treatment decisions for CLL patients are TP53 abnormalities and deletion 17p (del(17p)). These can mark a more aggressive disease that is harder to treat with standard CLL therapies.

A patient’s genetic makeup can influence treatment options during the treatment, or even before starting the treatment.

What Should Caregivers Monitor During Treatment?

Caregivers play a vital role for elderly patients during treatment for CLL and can monitor for changes and report to clinicians if needed.

Depending on the treatment, clinicians may monitor:

     Blood-cell counts

     Signs of infection

     Bleeding or bruising

     Heart-related symptoms

     Kidney function

     Liver function

     Medication interactions

     Treatment-related fatigue or other side effects

A list of the patient’s prescription medicines, over-the-counter products, and supplements can be maintained by caregivers. These can potentially cause an interaction with the treatment of the patient.

Caregivers must report new or unusual symptoms to the treating healthcare team.

Questions Caregivers Can Ask the CLL Care Team

Useful questions for the CLL Care Team appointment.

     Does the CLL currently require treatment?

     What is the goal of treatment?

     Which treatment options are appropriate for this patient?

     What test results influenced the treatment recommendation?

     Has genetic testing been performed?

     What side effects should the family watch for?

     Which symptoms require urgent medical attention?

     Are there interactions with the patient's existing medicines?

What should be the frequency of blood work check and monitoring?

     Are clinical trials appropriate?

Written notes can also be helpful to record information that the family needs to remember in order to follow the instructions given by the CLL Care Team, as well as remembering the dates and times of the family’s and patient’s future appointments for treatment and check-ups.

The Role of Supportive Care

Finally, CLL care includes more than leukemia control. Patients, especially of advanced age, often suffer from a variety of problems including frequent infections, decreased appetite and subsequent weight loss, extreme tiredness, depression, decreased mobility, and other co-existing health problems.

Supportive care to treat symptoms and problems of CLL can vary greatly from person to person. The caregiver needs to report any change in the patient’s physical condition or in their daily functioning, such as loss of appetite, or lack of energy, etc.

The Bottom Line

Current CLL treatments include targeted therapies, BTK inhibitors, and venetoclax-based combinations, as well as newly approved treatments for relapsed or refractory CLL, such as new agents for previously treated patients like pirtobrutinib, which was recently granted a traditional approval for a specific subset of previously treated CLL patients.

For older adults, the most appropriate treatment depends on individual patient and disease characteristics and may not necessarily be the latest treatment option. Individualized management of CLL, taking into consideration the patient’s specific leukemia, previous treatment, other health problems, other current diseases, potential drug toxicities and patient preferences is typical.

These forms of support can help caregivers play an active role throughout the treatment process

The CLL treatment of individual patients has to be decided by their qualified healthcare providers after thorough examination of their disease, overall health, as well as other coexisting medical conditions.
